TRUSS.

Specification of Letters Patent.

Patented Jan. 19, 1909.

Application filed June 26, 1908. Serial No. 440,448.

T 0 all whom it may concern:

Be it known that I, lViLLL-lii Lnxxox, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia I and State ofPennsylvania, have invented certain new and useful Improvements inTrusses, of which the following is a specification.

This invention relates to certain new and useful improvements in trussesand the particular object of the invention is to so mount the pressurepads that the same might be adjusted at the will of the operator whileon the person to increase or diminish the upward or downward pressure ofthe pads upon the hernia or other affected portion of the body.

Reference will be had to the accompanying drawing forming a part of thisspecification and wherein like numerals of reference designatecorresponding parts throughout the several views in which:

Figure 1, is a perspective view partly in section, and Fig. 2, is aninverted perspective view.

Reference numeral 1 designates the belt or body encircling band formedof spring strip metal having a suitable padded covering 2 which may bein the form of a permanent covering or a removable one formed bywrapping strips of soft material as stripchamois around the belt orband 1. One end of the belt or band 1 is provided with a number of holes3 through which is passed the end of flexible member 4 having a loopedend 5. The other end of the belt or band 1 is reduced and circular incross section as indicated by numeral 6, the extreme end being bent toform a hook 7 for engagement with the said loop 5 of the other or firstmentioned end. By adjusting the flexible member 4 in said openings 3,the size of the belt or band 1 may be varied.

Fixed to the circular or round portion 6 of the belt 1 by means of a pin8 is a collar 9 formed with peripheral ratchet teeth 10.

The pad plate 11 which is formed preferably of metal, is formed withopenings whereby the pad proper may be stitched to the plate, said padpreferably comprising a piece of folded chamois 14. One end of the padplate is formed with hinge barrels 15 which encircle the round end 6 ofthe belt, one on each side of the ratchet collar 9. To the pad plate ispivoted apawl 17 which is normally held in engagement with the ratchetteeth 10 by a spring 18 provided with a slot 19 and secured to the plateby screws 20 passing through the slot into the plate. By thisarrangement it will be apparent, that the truss pad may be swung uponthe round portion (3 of the belt 1 to the position necessary to properlyengage the hernia or affected part, and by means of the ratchetmechanism will be retained in such adjusted position. It will beapparent that to adjust the pad in one direction the spring 18 must beslid from engagement with the pawl, but such movement of the spring isunnecessary for adjusting the pad in the other direction.

Having fully described the invention. what is claimed as new and usefuland desired to be secured by Letters Patent is:

In a device of the character described, a body-encircling band having areduced portion circular in cross section and formed with a hooked end,a flexible adjustable loop member on the other end of the band adaptedto be engaged by the said hooked end, a hub rigid with the reducedportion of the band and being formed with ratchet teeth, a metal plateformed with integral hinge barrels loosely encircling the reduced end ofthe band one on each side of said hub, a pawl hinged at one of its endsto the plate and its other end being adapted to engage the teeth of thehub, a spring alined with said pawl and having a longitudinal slidingconnection with the plate and bearing at its free upon said pawl, theengagement of the pawl with the teeth and the pressure thereon beingcontrollable by said spring.

In testimony whereof I affix my signature in presence of two witnesses.

VILLIAM LENNOX.
